14048 if the attributes are target-dependent and they differ, we need to

14050 (build_qualified_type): A qualified type is not equivalent to its

14059 also build a canonical type reference.
14060 (build_index_type): When we can't hash an index type (e.g.,
14061 because its maximum value is negative), the index type requires
14062 structural equality tests.
14063 (build_array_type): Build the canonical form of an array type.
14064 (build_function_type): Function types require structural equality,
14065 because they contain default arguments, attributes, etc.
